Fix CPU profiling for Crankshaft.

The main issue was due to multiple recompilations of functions. Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.
tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).
DevTools CPU profiler treats all variants of function code as
a single function.
ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.
tickprocessor.py not updated -- it is deprecated and will be removed.

New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot.
...
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.
InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

Better align heap snapshots contents with debugger info.
...
I created a heap snapshot in Chromium, and then started comparing
it side-by-side with representations of objects provided by
the debugger, fixing discrepancies.

Fix HeapSnapshotsDiff test, diff implementation, and a bug introduced
...
during snapshot size optimization.
Sorry, now I figured out that the diff implementation itself was also
incorrect. Reachable nodes must be filtered from the beginning,
otherwise, an object that is already disconnected, but not discarded
yet, will not appear as a deleted (thankfully, this bug for some
reason had appeared on the x64 port.)
BUG=868
TEST=HeapSnapshotRootPreservedAfterSorting
